2.1.5 Lightning Protection Requirements

Although the F100-C-EI is designed to be lightning resistant, your

device can get damaged when excessive lightning is present. To

protect your device against lightning,

z Ensure the chassis is connected to earth ground.

z Ensure the ground point of the power socket is well

connected to earth ground.

z Add a lightning arrester to the front end of the power input to

better protect the power supply against lightning strikes.

2.1.6 Checking the Workbench

When installing the device on a workbench, make sure that:

z The workbench is firm enough to support the weight of the

device and its installation accessories.

z The workbench is well grounded.

2.1.7 Rack-Mounting Requirements

When installing the device in a rack, make sure that:

z The firewall is installed in an open rack. However, if you

want to mount it in a closed rack, make sure that the rack

has a good ventilation system.

z The rack is stable enough and can support the weight of the

firewall and the installation accessories;

z The rack dimensions meet the requirements for installing the

firewall. Adequate clearance is provided at the left and right

sides of the rack for good ventilation.
